Miniature Circuit Breaker(MCB) LYM16-63,
The state-of-art design
Elegant appearance; cover and handle in arc shape make comfortable operation.Contact posiion indicating window.Transparent
cover designed to carry label.
Handle central-staying function for circuit fault indicating
I In case of overioad, to protected circuit, MCB handle trips and stays at central posiion, which enables a quick solution to the faultyline. The handle cannot stay in such position when operatedmanually.
High short-circuit capacity
High short-circuit capacity 10KA for whole range and 15kA capacity for current rating up to 40A thanks to the powerful electricarc extinguishing system.Long electrical endurance up to 6000 cycles thanks to quick making mechanism.
Handle padlock device
MCB handle can be locked either at “ON” position or at”OFF” position to prevent unwanted operation of the product.
Screw terminal lock device
The lock deyice prevents unwanted or casual dismounting of connected terminals
